Seven days to go until the twenty-first century and somewhere in Taiwan the rain won't stop. A mysterious disease has reached epidemic proportions. A man in an apartment refuses to leave the quarantine zone. A plumber has been sent to check a leak for the downstairs neighbor. He leaves a sizeable hole in the middle of the man's room. The man doesn't seem to mind and he finds it useful for checking on his downstairs neighbor, a woman who stockpiles toilet paper. He quickly becomes fascinated by her, until she gets sick.
